To allcuhom it may concern:

Be it known that we, WALTER A. UNDER- HILL and COURTNEY (l. AVERY,citizens of the United States, and residents of Auburn, in the county ofCayuga and State of New York, have invented a certain new and usefulSteering Mechanism for l/Vagon-Trains,

of which the following is a specification. I

This invention hasfor-its object the production of. a mechanism forsteering a train ofv cartsufrom .the front end ofthe train whereby thecarts can be pushed in front of a traction engine or any other actuatingmeans, which steering mechanism is particularly simple in construction,economical in manufacture, readily attached in position on the carts,and highlyefiicient and durable in use, and the invention consists inthe novel combinations and constructions hereinafter set forth andclaimed.

In describing'thisinvention, reference is hadto'the accompanying drawingin which like characters designate corresponding parts in all the views.

Figure l is a plan view of a pair of twowheeled carts provided with ourinvention.

- pivotally connected to both carts so that the carts can be drawn whendesired, and one will trail behind the other when the carts areconnected with any suitable means for causin the rear cart to trail inthe tracks of the eading cart when turning a corner. The latter meanshas no bearing on the present invention and may be any suitable form,and one form is shown in our pending application Sr. No. 804,470, filedDecember 3, 1913. Means is provided by which the pivotal movement of thecoupling means and one cart isrendered ineffective to facilitate thepivotal movement of the other cart relatively to the coupling means toeffect the steering. Hence the tongue, so far as this invention isconcerned, is rigid with one cart.

1 and 2 are respectively the carts of a pair coupled together, as hereshown, by a tongue STEERING MECIJHANISM FOB, WAGON-TRAINS.

3 which is pivoted at 4 and 5 thereto respectively, the tongue extendingcentrally of the carts along the normal line of draft.

6 designates pins extending through openings in the platform 7 of onecart as the cart 2 on opposite sides of the tongue 3 in order tohold thetongue from pivotalmove ment relatively to one of said carts so that theother cart 1 is free to movepivotally to effect the steering.

The carts may be steered b the front or rear cart depen ing on whetherthe cart 1, which is pivoted to the coupling means, is the front or rearcart. The steering mechanism is preferably carried: by the couplin meansor tongue 3 and comprises a wind ass 9 carried by the tongue 3, andmeans as power transmitting elements or cables 10 extending in oppositedirections from the Windlass and winding in opposite directions thereon,the cables 10 being connected to brackets 11 rovided on the pivotedcart. 1 and located on the sides of the cart. 1 i

The Windlass 9 is mounted on a staff 12 journaled in brackets 13projecting from a slide 14 mounted on the coupling 3 and slidable ormovable alonga guideway '15 located beneath the platform 8 of the cartand extending crosswise of the tongue, the staff 12 havin a steeringwheel 16 at its upper end. The part 14 is capable of sliding slightly onthe draw bar 3 and also in the guide 15 in order to adjust itself to theangular relation of the draw bar 3 and the cart 1. The turning movementof the windlass is normally prevented by a toothed wheel 17 and a pawl18, the toothed wheel being mounted on the staff 12 above the upperbracket 13 and having square teeth and the pawl also having a squaretooth so that movement of the Windlass is prevented in oppositedirections. The pawl is movable into and out of operative position bythe foot of the operator.

This steering means is particularly applicable for two-wheeled cartsused in road making, as in building roads, it is desirable not to runthe heavy traction or road engine on the partly completed bed; and inoperation, the steering is accomplished by turning the rear cart 1whether the cart 1 is in front or second from the front.

What we claim is 1. The combination with a pair of two- Wheel carts, atongue connecting the carts and pivotally connected to the body of onecart and rigidly connected-to the body of the other cart, of mechanismfor turning one of the carts comprising a steeringmember supported bythe tongue and connections extending laterally in opposite directionsfrom'thesteering member and connected to the body of the cartOI].,QPPQSltBfiidGS'QOf.;l3he steering member, substantially as and forthe purpose set'forth. 1
